Travelling 11 lightyears in 10 years would require faster than light travel, which last time I checked is impossible in this version of the universe.

  You are talking about time in a frame at rest at either endpoint, not the frame of the ship/passenger, which relative to the rest frame is experiencing time dilation.

    ok, if we can have breakthroughs in propulsion (and braking) then that would be possible. My understanding is that acceleration gets exponentially more expensive at higher speeds making it practically unfeasible to build a ship like this
